如果您希望可以时常见面，欢迎标星收藏哦~ 来源：内容 编译自 wccftech ，谢谢 。 在半导体新元素的采用方面，台积电多年来一直是先驱，并经常引领潮流。但现在，该公司似乎将 放弃在其 A14 工艺中使用高数值孔径 EUV 光刻设备，而是采用更传统的 0.33 数值孔径 EUV 技 术。这一消息是在数值孔径技术研讨会上透露的，台积电高级副总裁Kevin Zhang在会上宣布了这 一进展。由此可以肯定地说，英特尔代工厂和几家 DRAM 制造商现在在"技术"上比台积电更具优 势。 Kevin 表示，台积电将不会使用High NA EUV光刻技术来对A14芯片进行图案化，该芯片的生产 计划于2028年开始。从2纳米到A14，我们不必使用High NA，但我们可以在处理步骤方面继续保 持类似的复杂性。他指出，每一代技术，我们都尽量减少掩模数量的增加。这对于提供经济高效的 解决方案至关重要。 台积电认为高数值孔径 (NA) 对 A14 工艺无关紧要的主要原因是，使用相关的光刻工具，这家台 湾巨头的成本可能会比传统的 EUV 方法高出 2.5 倍，这最终将使 A14 节点的生产成本大大提 高，这意味着其在消费产品中的 ...

来源：半导体产业纵横 ASML第一季度订单"令人失望"。 刚刚国家知识产权局信息显示，ASML 荷兰有限公司取得一项名为"用于晶片接地的方法、设备和系 统"的专利，授权公告号 CN114287051B，申请日期为 2020 年 8 月。 2023年末，三星与ASML签署了一项价值1万亿韩元的协议，双方将在韩国京畿道东滩投资建设半导体 芯片研究设施，并在那里共同努力改进EUV光刻制造技术。与此同时，三星还获得了High-NA EUV光 刻设备技术的优先权。 据TrendForce报道，ASML现在似乎放弃了与三星的合作建设半导体芯片研究设施，开始将早期购买的 土地出售。据了解，ASML在去年购入了6块土地，总面积达到了约19000平方米，其中2块已经出售， 另外2块在挂牌出售。至于具体什么原因，或者双方计划有什么改变，暂时还不清楚。 此举引发了外界对ASML与三星合作伙伴关系的质疑，不过有消息称，双方正在寻求更有效的替代方 案，比如寻找新地点另外建造研究设施，可能位于华城郊外，甚至可能选择在三星的园区内。由于韩国 是ASML的关键市场之一，随着三星推进先进制程节点的开发，双方应该会继续保持密切合作。根据 ASM ...
